Patent CA-2473220-A1 (CA)
Inventor: BELFORT GEORGES
IPC: C08J7/18
Filed: 2003-03-12
Abstract: A process for modifying a polymeric photoactive sulfone membrane includes placing the membrane into the presence of acrylic acid monomer dissolved in a solution and without sensitizer or free radical initiator and exposing the membrane to non-ionizing UV radiation for modifying the membrane by chemical grafting of the monomer at the surface of the membrane. The membrane can be polysulfone, polyethersulfone or polyarylsulfone. The radiation is selected to have an energy below that at which chain scission occurs and above that at which maximum grafting occurs. The process includes washing the modified membrane in a washing agent containing ethanol, glycol, ether, acid, hydrocarbon, or mixtures thereof, to wash homopolymer formed in the solution from the modified membrane, but preferably ethanol.

Title: Method and apparatus for one trip tubular expansion
Inventor: LYNDE GERALD D
IPC: E21B4/18
Filed: 2003-03-07
Abstract: A one trip system for expanding a tubular (176) that is solid or perforated or a screen is disclosed. The downhole assembly features a hydraulic anchor (10) that can be set, released and repositioned to repeat the process is used. The anchor (10) is small enough to go through the tubular (176) or screen after initial expansion. The anchor's maximum extension is designed to avoid overstressing the already expanded tubular or screen. An expansion tool (180) is hydraulically driven with the initial portion of the stroke delivering an enhanced force, the expansion tool (180) initially supports the tubular or liner but subsequently releases during the first stroke, after the tubular or screen is fully supported.

IPC: G01V7/16
Filed: 2003-03-06
Abstract: A method includes measuring an acceleration along an input axis (62a) of an accelerometer mounted to a gradiometer disc, the accelerometer having a coordinate axis that is parallel to a spin axis (Za) of the disc, and includes calculating a gravity tensor element as a function of the measured acceleration and a component of the measured acceleration caused by an acceleration along the coordinate axis. Consequently, this technique typically yields a more accurate calculation of the gravitational field by accounting for undesired accelerations picked up by accelerometers having input axes that are not parallel to the gradiometer disc.

Title: Pulsed-multiline excitation for color-blind fluorescence detection
Inventor: CURL ROBERT F
IPC: G01N21/78
Filed: 2002-08-28
Abstract: The present invention provides a technology called Pulse-Multiline Excitation or PME. This technology provides a novel approach to fluorescence detection with application for high throughput identification of informative SNPs, which could lead to more accurate diagnosis of inherited disease, better prognosis of risk susceptibilities, or identification of sporadic mutations. The PME  technology has two main advantages that significantly increase fluorescence sensitivity : (1) optimal excitation of all fluorophores in the genomic assay and (2) "color-blind" detection, which collects considerably more light than standard wavelength resolved detection. This technology differs significantly from the current state-of-the-art DNA sequencing instrumentation, which features single source excitation and color dipersion for DNA sequence identification. Successful implementation of the PME technology will have broad application for routine usage in clinical diagnostics, forensics, and general sequencing methodologies and will have the capability, flexibility, and portability of targeted sequence variation assays for a large majority of the population.

Title: Device and method for regenerating an electroless metal plating bath
Inventor: MURANUSHI MASANORI
IPC: C02F1/469
Filed: 2003-08-14
Abstract: In regenerating an electroless metal plating bath by electrodialysis, it has been found that the metal of the metal plating bath deposits in the electrolysis arrangement. To overcome this problem, an improvement to prior art regenerating devices is suggested, said improvement consisting in providing main cation exchangers for removing ions of this metal from a concentrate fluid. The main cation exchangers are coupled to the concentrate compartments of the electrolysis arrangement in such a manner that the concentrate fluid flowing through the concentrate compartments is allowed to pass through the main cation exchangers and to be recirculated back into the concentrate compartments.

Abstract: A method and apparatus for distributing broadcast quality video (or similar timing critical data) in the home over a network that is also carrying IP  traffic integrates non-IP video traffic with IP traffic in a seamless manner.  The present invention provides a method and apparatus for creating a network with mixed traffic, e.g., both timing critical traffic, such as MPEG type traffic, and IP traffic. The method transmits the timing critical data directly to a Media Access Control (MAC) layer and adds one or more specific functions to the Media Access Control to maintain timing restrictions of the timing critical data. The timing critical data can include an MPEG video data stream, and the one or more specific functions are then one or more MPEG  specific functions. An exemplary embodiment of a method for transmitting timing critical data, such as MPEG video data or 1394 traffic including isochronous video data, includes transmitting the timing critical data directly to a MAC layer, maintaining a timing relationship of the timing critical data throughout the MAC layer to a scheduler, and using a single scheduler to schedule transmission of both the timing critical data and the Internet Protocol traffic.

Abstract: Methods and apparatus for separating solid particles from a fluid. One preferred embodiment includes a tank for settling particles out of the fluid, a conical chamber at the bottom of the tank, an outlet connected to conical chamber, and a conical auger within the conical chamber. The tank may have a tangential inlet that creates a fluid circulation that exerts a centrifugal force on the solid particles to increase the settling of particles out of the fluid. The tank may have a static spiral on the inner wall that helps small particles coalesce into larger particles that settle faster out of the fluid.

Abstract: A method of washing an upflow filter (12) between service runs employs a filter bed (26) having a non-buoyant particulate filter layer (56) through which influent to be filtered is directed in an upward direction, and through which liquid employed in the washing operation is directed in an upflow direction. A two-stage washing operation includes the steps of first directing a combination of air and liquid in an upflow direction through the filter layer (56) with the velocity of the liquid being less than the minimum fluidization velocity of the filter layer (56), for disrupting only some floc retained in the filter layer during a previous service run, and thereafter directing only liquid in an up-flow direction through the filter layer at a velocity less than the minimum fluidization velocity of the filter layer for removing disrupted floc from the filter layer while leaving some floc attached to said particulate media of the filter layer. The process most preferably is carried out with a filter bed (26) including a coarse, particulate media flocculation layer (52) for distributing the flow of influent and promoting flocculation.
